Yes and no. Geany doesn't use all available lexers provided by
Scintilla. It uses only these which are needed for the
filetypes supported by Geany.

D, Java, C++ and C are highlighted by the C++ lexer LexCpp.
O-Matrix has its own lexer, LexOMS. LexOMS is not provided by
Scintilla, I derived it from LexBash, therefore the similarities ;-).

Why should we support all lexers of Scintilla? Crontab is a filetype I
didn't include in Geany. If someone is there who really wants it, we
can include it.

See src/highlighting.c, every defined filetype(with two or three
exceptions) of Geany has two functions in this file, where the Scintilla
lexer for this filetype is set.

Not really. To create a new filetype, many changes are needed. Maybe
this will change in the future but it will be a lot of hard work.
At the moment, the first step is to edit src/filetypes.c and its header
file, then editing src/highlighting.c and a few other things. Maybe,
the easier way is to send me as much information(esp. sample files)
about the filetype as you can and I will add it because I know where I
have to add something ;-).
Of course, if you really want to hack it on yourself, I will help you.


Have a nice weekend, I'm on the way getting out ;-).

Enrico

P.S.: one note on OMS:
Some time ago, someone from http://www.omatrix.com/ asked me to create a
filetype for their language. So I did and it is the OMS filetype. But
he didn't answered my last mails since months, so I'm thinking about to
remove this filetype because I think nobody use it.
